To be even more blunt: the concept of hell and the devil are attempts to explain why things go bad and why people act so horrribly towards each other (especially the faithful). Whenever something doesn't match the "goodness of god" you can scream out "The devil made me do it!"I'm just going to ask bluntly... what evidence is there in the cosmos that hell exists? People can point to feelings and miraculous events as evidence of a God. But what events do we have supporting the notion of a hell? What evidence? What logic? What experience? Or might it just be easier just to say that hell is a cultural belief? Like the North Pole or Valhalla? This concept of hell seems to be the "fear" by which Christians can scare people into their belief system. "Believe our beliefs, or else..."
You are arguing a lost cause here. People of faith are all too often ashamed to admit that their beliefs are, indeed, faith and not provable by any logical means. This is a silly feeling to have as faith is certainly one of the ways to look at the universe. Some prefer the logical, some the supernatural, some the emotional, some the philosophical. Yet its those who believe in the supernatural that fight the hardest to "logically prove" the road they have chosen.
